In another report. Park et al. have successfully fabricated a cell-free protein-producing gel that can produce proteins 300 times more efficiently than existing solution processes [87]. Ligation of the gene of interest, in this case the renilla luciferase gene, with X-DNA connectors by DNA Hgase yielded a protein-producing...

Fig. 16 Panel for ligand-attached PEG-siRNA conjugate through the acid-labile linkage system, a Chemical structure of Lac-PEG-siRNA conjugate, which is readily cleaved at the pH corresponding to that of the endosome (pH 5.5). b Evaluahon of RNAi activities against the firefly luciferase coded gene in cultured HuH-7 cells under various conditions. Normalized ratios between the firefly luciferase activity (firefly luc.) and the renilla luciferase activity (renilla luc.) are shown as ordinate ( = 3, SD)...

Glow luminescence techniques have been used extensively with luciferases as reporter genes in cell-based assays. An overview of such assays is given in Section 10.3.2 Reporter Assays below. Luciferases are enzymes which catalyze bio-luminescent reactions. Two forms are used as reporters, one originating from the firefly (firefly luciferase) and the other from Rmilla (Renilla luciferase). Due to their different origins, the enzyme structures and their respective substrates are quite different While Rmilla luciferase catalyzes the oxidation of coelenterazine, the substrate of firefly luciferase is the beetle luciferin, which is oxidized in the presence of ATP and Mg as depicted in Fig. 17. 

While the applications of SELP-mediated controlled gene delivery are numerous, we have focused our efforts on controlled delivery to solid tumors. Our initial studies in this arena involved the intratumoral delivery of a reporter plasmid Renilla luciferase) to solid tumors in a murine (athymic nu/nu) model of human breast cancer (MDA-MB-435 cell line) (50). Delivery of the Renilla luciferase plasmid from SELP-47K matrices resulted in significantly enhanced tumor transfection for up to 21 days compared to naked DNA (Fig. 5). In particular, delivery of the plasmid from matrices containing 4 or 8 wt.% polymer resulted in enhanced transfection...
